The case pertains to allocation of Amarkonda Murgadangal coal block in Jharkhand. The names of these five people were revealed by Suresh Singhal, a chartered accountant who was earlier chargesheeted by the CBI as accused in the case.

The court had summoned them also as accused after taking cognisance of the supplementary chargesheet filed by the CBI on March 24. Besides Mr Jindal, the case also involves former Minister of State for Coal Dasari Narayan Rao and ex-Jharkhand Chief Minister Madhu Koda.

The court had earlier directed the CBI to expeditiously file its further probe report. The CBI had alleged that Mr Koda had favoured Jindal group firms - Jindal Steel and Power Limited (JSPL) and Gagan Sponge Iron Private Limited (GSIPL) - in allocation of Amarkonda Murgadangal coal block in Jharkhand.

All the accused had denied the allegations levelled against them. They had claimed that there was no evidence to show conspiracy during coal block allocation.
